Referring to fig. 1 and 2, the chair back 3 includes a flexible mesh layer 9, a support bar 10 for supporting the flexible mesh layer 9, and a lumbar support 11 for supporting office staff. Flexible netted cloth layer 9 fixed connection is in the up end of bottom plate 6, and is concrete, and flexible netted cloth layer 9 includes that integrated into one piece locates the screen cloth 13 on back of the body frame 12 and the cover on back of the body frame 12 on bottom plate 6, and is 95 contained angles setting between back of the body frame board and the bottom plate 6, and screen cloth 13 weaves fixedly with foam-rubber cushion 8.

The support rod 10 is fixed on the lower end face of the bottom plate 6 through bolts, and one end of the support rod 10, which is far away from the bottom plate 6, is also fixed with one end of the flexible mesh layer 9, which is far away from the bottom plate 6, through bolts. In addition, a sliding groove 14 is formed in one side, close to the flexible mesh layer 9, of the support rod 10, a connecting piece 15 is arranged on one side, close to the support rod 10, of the waist support 11, and the connecting piece 15 slides in the sliding groove 14 in a limiting mode.

Before the office staff need do official working, the office staff can adjust the position that the waist held in the palm 11 through connecting piece 15, and then holds in the palm 11 with the waist and slide to the position that is fit for oneself size, and then improves office chair's comfort level. The spongy cushion 8 and the flexible netted cloth layer 9 provide a flexible support for office workers, and the heat dissipation effect of the flexible netted cloth layer 9 further improves the comfort level of the office chair.

Referring to fig. 2 and 3, the connection member 15 includes a dovetail block 16, a connection block 17 integrally formed on the dovetail block 16, and a plurality of hand-held posts 18 provided on the connection block 17. The dovetail block 16 is limited to slide in the sliding groove 14, the inclined surface of the dovetail block 16 is abutted against the groove wall of the sliding groove 14, and one end of the connecting block 17 far away from the dovetail block 16 is fixedly connected with the waist support 11.

In addition, one side of the support bar 10 close to the waist support 11 is provided with an installation groove 19 for placing the dovetail block 16 and a plurality of limiting grooves 20 for limiting the movement of the dovetail block 16, in this embodiment, the installation groove 19 is communicated with one end of the sliding groove 14, and one limiting groove 20 is provided, and the other end of the limiting groove 20 is communicated with the other end of the sliding groove 14.

Specifically, mounting groove 19 communicates each other with the one end that the groove 14 that slides is close to bottom plate 6, and interference is connected with stopper 21 in the mounting groove 19, and the lower lateral wall of dovetail piece 16 and the last lateral wall of stopper 21 butt each other, and then when making the installation to waist support 11 more simple and convenient, can also reduce the possibility that waist support 11 and bracing piece 10 take place to break away from.

The limiting groove 20 is communicated with one end of the sliding groove 14 far away from the limiting block 21, and the groove width of the limiting groove 20 is smaller than that of the sliding groove 14. Specifically, in the present embodiment, the two opposite groove walls of the limiting groove 20 gradually approach each other in a direction away from the sliding groove 14.

When the dovetail block 16 slides to the position of the limit groove 20, the groove wall of the limit groove 20 firstly gives a guiding function to the dovetail block 16, and then the dovetail block 16 is forced to be inserted into the limit groove 20 in an interference manner. In the embodiment, the dovetail block 16 is made of polyethylene, so that the dovetail block 16 has a certain elasticity, and at this time, the slot wall of the limiting slot 20 forces the dovetail block 16 to deform, so that the slot wall of the limiting slot 20 can limit the movement of the dovetail block 16, and further the possibility of relative sliding of the waist support 11 is reduced.

The plurality of handheld columns 18 are screwed on the outer side wall of the connecting block 17, in the embodiment, the number of the handheld columns 18 is two, and the two handheld columns 18 are respectively arranged on the two horizontal side walls of the connecting block 17. In addition, the end of each holding column 18 far away from the connecting block 17 is provided with a holding part 22, so that when the dovetail block 16 needs to be controlled, the holding part 22 gives a holding point to an office worker, and further the control of the dovetail block 16 is facilitated.

Referring to fig. 3 and 4, the waist support 11 comprises a supporting plate 23 and a connecting frame 24 integrally formed on one side of the supporting plate 23 close to the connecting block 17, and one side of the connecting frame 24 far away from the supporting plate 23 is rotatably connected with one end of the connecting block 17 far away from the dovetail block 16.

Specifically, a connecting seat 25 is integrally formed on one side of the connecting frame 24, which is far away from the waist support 11, a rotating groove 26 is formed on one side of the connecting seat 25, which is far away from the connecting frame 24, and one side of the connecting block 17, which is far away from the dovetail block 16, is rotatably connected in the rotating groove 26.

Specifically, two opposite groove walls of the rotating groove 26 are provided with rotating holes 27 in a penetrating manner, and the two handheld columns 18 are respectively provided with two rotating holes 27 in a penetrating manner and are in threaded connection with the connecting block 17. The handheld portion 22 is sleeved on one end of the handheld column 18 far away from the connecting block 17 in an interference manner, and one side of the handheld portion 22 close to the connecting block 17 abuts against the outer side wall of the connecting seat 25.

In addition, one side of the connecting block 17, which is far away from the dovetail block 16, is provided with a rounded corner 28, so that when the angle of the waist support 11 needs to be controlled, the supporting plate 23 can be directly controlled through the connecting seat 25, and the control of the waist support 11 is simpler and more convenient. And the arrangement of the rounding 28 reduces the influence of the connecting block 17 on the rotation of the waist support 11.

Referring to fig. 2 and 4, one side of the supporting plate 23 away from the connecting frame 24 is provided with an arc surface 29, and the arc surface 29 is provided with a plurality of through grooves 30 in a penetrating manner, and the number of the through grooves 30 can be set according to actual conditions. When office workers work in offices, the arc surface 29 gives the office workers smooth protection, the through groove 30 dissipates heat to the office workers, and the comfort level of the office chair is further improved.

The implementation principle of the adjustable office chair with the waist support in the embodiment of the application is as follows:

before the office staff need do the official working, office staff can control connecting block 17 through handheld portion 22, and connecting block 17 drives dovetail block 16 and slides to the assigned position. When the dovetail block 16 slides to the position of the limit groove 20, the groove wall of the limit groove 20 limits the movement of the dovetail block 16, thereby completing the change of the position of the waist support 11.

Directly pass through connecting seat 25 afterwards and alternate the angle that the waist held in the palm 11, and then carry out the adaptation with waist support 11 and office staff's size, and then improve office chair's comfort level.

The spongy cushion 8 and the flexible netted cloth layer 9 provide a flexible support for office workers, and the heat dissipation effect of the flexible netted cloth layer 9 further improves the comfort level of the office chair.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
